Abstract
BACKGROUND Polyurethane (PU)-coated breast implants are known for their strong integration into breast tissue and the formation of capsules around them. However, capsular contracture can pose both aesthetic and clinical challenges. OBJECTIVES The objectives of this study were to analyze the biological and morphological characteristics of the capsular tissue surrounding PU-coated implants, irrespective of their contracture status, and to assess their potential suitability as a flap in revisional breast surgery for capsular contracture. METHODS A total of 23 tissue samples were harvested from the capsules surrounding PU-coated breast implants in 12 female patients during replacement or revisional surgery. We evaluated collagen abundance, cellular and vascular density, inflammation, collagen band types and alignment, synovial metaplasia, capsule thickness, and the expression of inflammatory biomarkers and myofibroblasts with immunohistochemical techniques. Scanning electron microscopy was employed to assess implant surface characteristics over time. RESULTS We found a significant association of capsule contraction with longer implantation durations and greater implant surface roughness (P = .018 and P = .033, respectively). Synovial metaplasia was significantly more frequent in noncontracted capsules (P = .0049). Both capsule types consisted of paucicellular, type I collagen-rich compact fibrous tissue with low vascularization. There was a marked reduction in inflammatory cells within the foreign body granuloma. The expression of inflammatory biomarkers in the capsular tissue was negligible. CONCLUSIONS Given the reduced levels of inflammatory and vascular components within the dense, fibrous capsular tissue, we consider them to be viable alternatives for capsular flaps in revisional surgery. This strategy has the potential to mimic the reconstruction achieved with acellular dermal matrix. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Capsular contracture (CC) is a common complication following implant-based breast surgery, often requiring surgical intervention. Yet, little is known about risk factors and outcomes following CC surgery. METHODS We reviewed the American College of Surgeons National Surgical Quality Improvement Program database (2008-2021) to identify female patients diagnosed with CC and treated surgically. Outcomes of interest included the incidence of surgical and medical complications at 30-days, reoperations, and readmissions. Confounder-adjusted multivariable analyses were performed to establish risk factors. RESULTS 5,057 patients with CC were identified (mean age: 55 ± 12 years and mean body mass index [BMI]: 26 ± 6 kg/m2). While 2,841 (65%) women underwent capsulectomy, capsulotomy was performed in 742 patients (15%). Implant removal and replacement were recorded in 1,160 (23%) and 315 (6.2%) cases, respectively. 319 (6.3%) patients experienced postoperative complications, with 155 (3.1%) reoperations and 99 (2.0%) readmissions. While surgical adverse events were recorded in 139 (2.7%) cases, 86 (1.7%) medical complications occurred during the 30 day follow-up. In multivariate analyses, increased BMI (OR: 1.04; p = 0.009), preoperative diagnosis of hypertension (OR: 1.48; p = 0.004), and inpatient setting (OR: 4.15; p < 0.001) were identified as risk factors of complication occurrence. CONCLUSION Based on 14 years of multi-institutional data, we calculated a net 30 day complication rate of 6.3% after the surgical treatment of CC. We identified higher BMI, hypertension, and inpatient setting as independent risk factors of postoperative complications. Plastic surgeons may wish to integrate these findings into their perioperative workflows, thus optimizing patient counseling and determining candidates' eligibility for CC surgery.

Abstract
BACKGROUND In breast surgeries, a lactiferous duct leading to lactic glands of breast parenchyma allows direct contamination by normal bacterial flora of the nipple-areola complex. Complete blockage of nipple flora from the intraoperative field is almost impossible. OBJECTIVES We aimed to analyze the microbiological profile of nipple flora of breast cancer patients who underwent an implant-based immediate breast reconstruction after a total mastectomy, and to evaluate the association of nipple bacterial flora with postoperative complications. METHODS A retrospective chart review was performed of patients who underwent an implant-based immediate breast reconstruction after a total mastectomy. A nipple swab culture was performed preoperatively. Patient demographics, surgical characteristics, and complications were compared between positive and negative nipple swab culture groups. Microbiological profile data including antibacterial resistance were collected. RESULTS Among 128 breasts, 60 cases (46.9%) had positive preoperative nipple swab culture results. Staphylococcus epidermidis accounted for 41.4% of microorganisms isolated. A multivariate logistic regression analysis of postoperative complications revealed that the presence of nipple bacterial flora was a risk factor for capsular contracture. Seven cases of postoperative infection were analyzed. In 2 cases (40% of pathogen-proven infection), the causative pathogen matched the patient's nipple bacterial flora, which was methicillin-resistant S. epidermidis in both cases. CONCLUSIONS Nipple bacterial flora was associated with an increased risk of capsular contracture. Preoperative analysis of nipple bacterial flora can be an informative source for treating clinically diagnosed postoperative infections. More studies are needed to determine the effectiveness of active antibiotic decolonization of the nipple. LEVEL OF EVIDENCE: 3

Abstract
Introduction Breast augmentation, a popular cosmetic surgery using devices like silicone implants, can lead to a common issue called capsular contracture (CC). This condition involves the formation of fibrous tissue around the implants and can be influenced by variables like immunological and bacterial factors. This study aimed to explore the impact of autoimmune diseases (ADs) on CC along with other factors influencing future clinical decisions. Methods A systematic review of electronic databases was conducted using PubMed, Web of Science, Scopus, EMBASE, and involving adult patients (>18) with CC and ADs after breast surgery using MeSH terminology using a broad search strategy. All searches were performed and analyzed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and duplicates were removed with Rayyan. Two independent investigators extracted and assessed the data involving demographics and baseline data related to CC and AD. Results The incidence of CC varied (2.3%-4.1%). Subglandular placement and older device age raised risk. SERI Surgical Scaffold complications included necrosis, seroma, hematoma, implant loss, and infection; CC was associated with necrosis. Natrelle 410 implants showed lower 10-year CC risk than round gel implants. Acellular dermal matrix implant-based breast reconstruction with radiotherapy (RT) correlated with 20.7% post-RT CC. Previous research demonstrated no significant connection between silicone gel implants and ADs. Biofilm, surgical site infection, implant features, and interventions emerged as frequent CC risk factors. Conclusion Finding appropriate techniques to reduce the risk factors associated with CC together with providing comprehensive patient counseling on these factors will definitely improve the patient-centered outcome of breast implant surgery.

Abstract
Breast implant-associated anaplastic large cell lymphoma has been recognized as a distinct entity in the World Health Organization classification of hematolymphoid neoplasms. These neoplasms are causally related to textured implants that were used worldwide until recently. Consequently, there is an increased demand for processing periprosthetic capsules, adding new challenges for surgeons, clinicians, and pathologists. In the literature, the focus has been on breast implant-associated anaplastic large cell lymphoma; however, benign complications related to the placement of breast implants occur in up to 20% to 30% of patients. Imaging studies are helpful in assessing patients with breast implants for evidence of implant rupture, changes in tissues surrounding the implants, or regional lymphadenopathy related to breast implants, but pathologic examination is often required. In this review, we couple our experience with a review of the literature to describe a range of benign lesions associated with breast implants that can be associated with different clinical presentations or pathogenesis and that may require different diagnostic approaches. We illustrate the spectrum of the most common of these benign disorders, highlighting their clinical, imaging, gross, and microscopic features. Finally, we propose a systematic approach for the diagnosis and handling of breast implant specimens in general.

Abstract
OBJECTIVE Search the Manufacturer and User Facility Device Experience database to collect information on adverse events of breast implant. We analyzed the local complications and the breast implant illness (BII) of silicone breast implants, as well as saline breast implants separately, aim to provide a reference for women who want to breast augmentation. MATERIALS AND METHODS The Manufacturer and User Facility Device Experience database was queried for events reports related to the breast implant between July 1, 2012, and June 30, 2022. Event year and reporting year were summarized. Patient problem was collected and analyzed to distinguish between local complications and BII. RESULTS A total of 108,728 adverse events in the past 3 years were analyzed, silicone breast implants accounted for 62.1% and saline breast implants accounted for 37.9%. The most common local complication of women receiving silicone breast implants was "Capsular Contracture," accounting for 48.73%. However, the incidence of "capsular contracture" in women who received saline breast implants was only 17.49%. The most common BII was "fatigue/weakness" in both women receiving 2 different breast implants, 17.20% in women receiving silicone breast implants and 24.71% in women receiving saline breast implants. Of note, in all the reports, there was a wide variation in the timing of reporting as compared with the timing of the adverse event. CONCLUSIONS Although the adverse events of breast implant cannot completely be determined from this study, we provide a reference for women who want to get breast implants, so that they can choose breast implants more carefully. In addition, a better understanding of BII may allow them to think further about whether the benefits of breast implants outweigh the risks.

Abstract
BACKGROUND Esthetic complications, such as capsular contracture and soft-tissue contour defects, hinder the desired outcomes of breast reconstruction. As subclinical infection is a prevailing theory behind capsular contracture, we investigated the effects of post-operative infections on these issues and revision procedures. METHODS We conducted a retrospective database study (2007-2021) on breast reconstruction patients from the MarketScan® Databases. Esthetic complications were defined by their associated revision procedures and queried via CPT codes. Severe capsular contracture (Grade 3-4) was defined as requiring capsulotomy or capsulectomy with implant removal or replacement. Moderate and severe soft-tissue defects were determined by the need for fat grafting or breast revision, respectively. Generalized linear models were used, adjusting for comorbidities and surgical factors (p < 0.05). RESULTS We analyzed the data on 62,510 eligible patients. Post-operative infections increased the odds of capsulotomy (OR 1.59, p < 0.001) and capsulectomy (OR 2.30, p < 0.001). They also raised the odds of breast revision for severe soft-tissue defects (OR 1.21, p < 0.001). There was no significant association between infections and fat grafting for moderate defects. Patients who had post-operative infections were also more likely to experience another infection after fat grafting (OR 3.39, p = 0.0018). In two-stage reconstruction, infection after tissue expander placement was associated with greater odds of infection after implant placement. CONCLUSION Post-operative infections increase the likelihood of developing severe soft-tissue defects and capsular contracture requiring surgical revision. Our data reinforce the role of infections in the pathophysiology of capsular contracture. Additionally, infections elevate the risk of subsequent infections after fat grafting for moderate defects, further increasing patient morbidity.

Abstract
Background Breast augmentation is one of the most commonly performed aesthetic surgery procedures. Yet, few reports in the literature analyze individual surgeon experiences with a unified surgical method on a large group of patients. This study aimed to analyze a single surgeon's complications rate and experience with the Akademikliniken augmentation mammaplasty method from the beginning of his career. Methods A retrospective outcome analysis of all patients (n = 1646) who underwent breast augmentation between 2009 and 2021 performed by a single surgeon was conducted. Complications and reoperation rates were evaluated. In addition, correlations with the patient and implant characteristics and insertion-method-related risk factors were analyzed. Results In total, 1212 female patients (mean age, 31.47 years) were analyzed. The minimal follow-up for every patient was 6 months (mean follow-up, 18.35 months). The total complication rate was 7.1%, and the most common complication (2.64%) was capsular contracture (Baker scale III/IV). Implant insertion with a funnel significantly lowered the overall risk of complications (P = 0.009). Statistical analysis indicates that the single independent risk factors for primary breast augmentation are patient age younger than 27 years, initial breast size B and C, and tobacco smoking. Conclusions This study indicated that capsular contracture and implant rotation are the most common complications of analyzed primary augmentation mammoplasty. It also identifies various risk and protection factors, such as funnel usage, which should be considered by the surgeon when performing this type of procedure.

Abstract
INTRODUCTION Despite a lack of data demonstrating causation, there is growing concern over breast implants and systemic illness. This study examines the impact of rising public interest in breast implant illness (BII) and its implications on breast implant removals (BIR). METHODS A Google Trends (GT) analysis of each year between 2010 and 2022 was performed globally, and then separately for the United States alone (US), using the search terms "capsular contracture," "breast implant illness," and "breast implant(s) removal". Linear regression was performed to determine significant correlations. Data on BII-related Facebook advocacy groups, relevant pop culture events, numbers of BIR surgeries, and number of BII-related publications were collected and analyzed alongside GT data to determine relevance. RESULTS For global GT, there was a significant relationship between "breast implant illness" and "breast implant(s) removal" in 2016 (R2=0.62, β =0.33, p<0.01), 2020 (R2=0.53, β =0.23, p=0.01), and 2022 (R2=0.60, β =0.44, p=0.01). In the US, 2016 (R2=0.53, β =1.75, p=0.01) 2018 (R2=0.61, β =1.93, p<0.01) and 2020 (R2=0.72, β=0.91, p<0.01) were significant. In 2020, "capsular contracture" and "breast implant(s) removal" was significant in the US (R2=0.58, β=0.4, p=0.01). In 2016, Facebook was the platform for the largest BII advocacy group and in 2020 YouTube was the platform for the first BII documentary and TEDx talk. From 2010 to 2020, PubMed publications containing "ASIA" and "BII" increased 24-fold and ASPS reports on BIR rose 70%. CONCLUSION This study suggests that BII is a topic of global concern and has implications on both academic medicine and clinical practice.

Abstract
Background and Objectives: The surge in breast-related surgeries in Korea underscores the critical need for an accurate early diagnosis of silicone breast implant-related issues. Complications such as BIA-ALCL and BIA-SCC add complexity to breast health concerns, necessitating vigilant monitoring. Despite advancements, discrepancies persist between ultrasonographic and pathologic classifications of silicone implant ruptures, highlighting a need for enhanced diagnostic tools. This study explores the reliability of ultrasonography in diagnosing silicone breast implant ruptures and determining the extent of silicone migration, specifically with a focus on guiding potential capsulectomy based on pathology. Materials and Methods: A comprehensive review of medical records encompassing 5557 breast implants across 2790 patients who underwent ultrasound-assisted examinations was conducted. Among the screened implants, 8.9% (249 cases) were diagnosed with silicone breast implant rupture through ultrasonography. Subsequently, 89 women underwent revisional surgery, involving capsulectomy. The pathological analysis of 111 periprosthetic capsules from these cases aimed to assess the extent of silicone migration, and the findings were juxtaposed with the existing ultrasonographic rupture classification. Results: The diagnostic agreement between preoperative sonography and postoperative findings reached 100% for silicone breast implant ruptures. All eighty prosthetic capsules exhibiting a snowstorm sign in ultrasonography demonstrated silicone migration to capsules upon pathologic findings. Conclusions: High-resolution ultrasonography emerged as a valuable and reliable imaging modality for diagnosing silicone breast implant ruptures, with a notable ability to ascertain the extent of free silicone migration to capsules. This diagnostic precision is pivotal in informing decisions about potential capsulectomy during revisional surgery. The study advocates for an update to the current binary ultrasonographic classification, suggesting a more nuanced categorization into three types (subcapsular, intracapsular, and extracapsular) based on pathology.

Consulting the Digital Doctor: Google Versus ChatGPT as Sources of Information on Breast Implant-Associated Anaplastic Large Cell Lymphoma and Breast Implant Illness. Aesthetic Plast Surg 2024; 48:590-607. [PMID: 37903939 DOI: 10.1007/s00266-023-03713-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 10/10/2023] [Indexed: 11/01/2023]
Abstract
BACKGROUND Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare complication associated with the use of breast implants. Breast implant illness (BII) is another potentially concerning issue related to breast implants. This study aims to assess the quality of ChatGPT as a potential source of patient education by comparing the answers to frequently asked questions on BIA-ALCL and BII provided by ChatGPT and Google. METHODS The Google and ChatGPT answers to the 10 most frequently asked questions on the search terms "breast implant associated anaplastic large cell lymphoma" and "breast implant illness" were recorded. Five blinded breast plastic surgeons were then asked to grade the quality of the answers according to the Global Quality Score (GQS). A Wilcoxon paired t-test was performed to evaluate the difference in GQS ratings for Google and ChatGPT answers. The sources provided by Google and ChatGPT were also categorized and assessed. RESULTS In a comparison of answers provided by Google and ChatGPT on BIA-ALCL and BII, ChatGPT significantly outperformed Google. For BIA-ALCL, Google's average score was 2.72 ± 1.44, whereas ChatGPT scored an average of 4.18 ± 1.04 (p < 0.01). For BII, Google's average score was 2.66 ± 1.24, while ChatGPT scored an average of 4.28 ± 0.97 (p < 0.01). The superiority of ChatGPT's responses was attributed to their comprehensive nature and recognition of existing knowledge gaps. However, some of ChatGPT's answers had inaccessible sources. CONCLUSION ChatGPT outperforms Google in providing high-quality answers to commonly asked questions on BIA-ALCL and BII, highlighting the potential of AI technologies in patient education.

Abstract
Once believed to be completely inert implants, Silicon Breast Implants (SBIs) have been shown to be able to induce a chronic inflammatory response in the body which can lead to a variety of possible manifestations ranging from the most common capsular contraction to rarer conditions such as malignancies and autoimmune diseases. Among the latter, new syndromes have been consistently recognized: Breast Implant Illness (BII) and autoimmunity/autoinflammatory syndrome induced by adjuvants (ASIA syndrome/Shoenfeld's Syndrome). The pathophysiological mechanisms underlying such syndromes are not yet clear and the overlap they show with other common conditions have sparked an important debate in the scientific community regarding their existence and their cause-effect relationship with SBIs. In this article Professor Cohen Tervaert and Professor Bassetto, leading experts in the field, are going to present arguments in favor and against such causal relationship according to the latest scientific evidence. Professor Cohen Tervaert is going to demonstrate how the evidence available is enough to prove a causal relationship as defined by the Bradford Hill's criteria. Professor Bassetto is going to highlight how the many biases that afflict the available evidence prevent us from drawing such conclusions. Professor Shoenfeld is going to moderate the discussion with its insightful conclusions.

Abstract
Background Two-stage breast reconstruction is a common technique used to restore preoperative appearance in patients undergoing mastectomy. However, capsular contracture may develop and lead to implant failure and significant morbidity. The objective of this study is to build a machine-learning model that can determine the risk of developing contracture formation after two-stage breast reconstruction. Methods A total of 209 women (406 samples) were included in the study cohort. Patient characteristics that were readily accessible at the preoperative visit and details pertaining to the surgical approach were used as input data for the machine-learning model. Supervised learning models were assessed using 5-fold cross validation. A neural network model is also evaluated using a 0.8/0.1/0.1 train/validate/test split. Results Among the subjects, 144 (35.47%) developed capsular contracture. Older age, smaller nipple-inframammary fold distance, retropectoral implant placement, synthetic mesh usage, and postoperative radiation increased the odds of capsular contracture (p < 0.05). The neural network achieved the best performance metrics among the models tested, with a test accuracy of 0.82 and area under receiver operative curve of 0.79. Conclusion To our knowledge, this is the first study that uses a neural network to predict the development of capsular contraction after two-stage implant-based reconstruction. At the preoperative visit, surgeons may counsel high-risk patients on the potential need for further revisions or guide them toward autologous reconstruction.

Abstract
Background In this study, we established two rat models that mimic human submuscular and premuscular breast reconstruction. We analyzed the capsule formation according to surgical techniques and adjacent tissues, including the chest wall tissues, such as the ribs and acellular dermal matrices (ADMs) that come in contact with silicone implants. Methods This study consisted of experiments on 12 Sprague-Dawley rats that underwent implant reconstruction using ADM. They were divided into two groups: rats that underwent dual-plane implantation (n = 6; group 1) and those that underwent premuscular implant insertion (n = 6; group 2). All rats were irradiated with 35 Gy of fractionated radiation. Three months after surgery, the histology and immunochemistry of the capsule tissues of the ADM, muscle, and chest wall were analyzed. Results Overall capsule thickness was thicker in group 1. Based on the tissue in contact with the silicone implant, ADM had a thinner capsule, less inflammation, less fibrosis, and less vascularization than the muscle and chest wall tissues. Conclusions This study described two rat models of clinically relevant implant-based breast reconstruction using a submuscular and premuscular plane, ADM, and irradiation. Overall, the premuscular implantation rat model was associated with a thinner capsule. The ADM in contact with the silicone implant, even after irradiation, had superior protection from radiation compared with the other tissues.

Abstract
Background The ideal breast implant does not exist and the choice of implant for breast augmentation is largely based on what surgeons think will be best for their patients. Objectives To evaluate the preliminary results of a new, smooth, round, and opaque breast implant (PERLE, GC Aesthetics; Dublin, Ireland) from a single-center UK aesthetic practice. Methods Retrospective cohort study of all patients undergoing breast implant surgery with PERLE at the authors' center between January 2021 and December 2022. Outcomes data such as rates of capsular contracture, infection, revision surgery, and synchronous mastopexy were analyzed. Results Of the 385 patients identified, 374 (97.1%) had PERLE implants placed by 3 surgeons for primary (n = 290) and secondary breast augmentation (n = 21), and augmentation-mastopexy (n = 63). Capsular contracture occurred in no cases, infection in 1 (0.2%), and revision surgery in 21 patients (5%). The incision used was always submammary, unless a synchronous mastopexy was performed; implants were placed in the subglandular/subfascial plane in the majority of cases (85.3%), and the rest were dual plane (14.7%). Eight revisions were performed in patients undergoing breast augmentation (due to implant displacement in 6 patients, and hematoma and infection in 1 patient each). Fourteen revisions were performed in those undergoing augmentation-mastopexy. The average follow-up time was 18 months. Conclusions The authors' early, single-center experience with PERLE implants suggests a safety profile and overall complication rate that is comparable with other modern implants. They will continue to monitor the safety and effectiveness of PERLE and discuss the reasons and evolution in the choice of breast implant. Level of Evidence 4

Abstract
The incidence of breast cancer and, therefore, the need for breast reconstruction are expected to increase. The many reconstructive options available and the changing aspects of the field make this a complex area of plastic surgery, requiring knowledge and expertise. Two major types of breast reconstruction can be distinguished: breast implants and autologous flaps. Both present advantages and disadvantages. Autologous fat grafting is also commonly used. MRI is the modality of choice for evaluating breast reconstruction. Knowledge of the type of reconstruction is preferable to provide the maximum amount of pertinent information and avoid false positives. Early complications include seroma, hematoma, and infection. Late complications depend on the type of reconstruction. Implant rupture and implant capsular contracture are frequently encountered. Depending on the implant type, specific MRI signs can be depicted. In the case of myocutaneous flap, fat necrosis, fibrosis, and vascular compromise represent the most common complications. Late cancer recurrence is much less common. Rarely reported late complications include breast-implant-associated large cell anaplastic lymphoma (BIA-ALCL) and, recently described and even rarer, breast-implant-associated squamous cell carcinoma (BIA-SCC). In this review article, the various types of breast reconstruction will be presented, with emphasis on pertinent imaging findings and complications.

Abstract
Biomaterials, when implanted in the human body, can induce a series of cell- and cytokine-related reactions termed foreign body reactions (FBRs). In the progression of FBRs, macrophages regulate inflammation and healing by polarizing to either a pro-inflammatory or pro-healing phenotype and recruit fibroblasts by secreting cytokines. Stimulated by the biomaterials, fibrotic capsule is formed eventually. The implant, along with its newly formed capsule, introduces various mechanical cues that influence cellular functions. Mechanosensing proteins, such as integrins or ion channels, transduce extracellular mechanical signals into cytoplasm biochemical signals in response to mechanical stimuli. Consequently, the morphology, migration mode, function, and polarization state of the cells are affected. Modulated by different intracellular signaling pathways and their crosstalk, the expression of fibrotic genes increases with fibroblast activation and fibroblast to myofibroblast transition under stiff or force stimuli. However, summarized in most current studies, the outcomes of macrophage polarization in the effect of different mechanical cues are inconsistent. The underlying mechanisms should be investigated with more advanced technology and considering more interfering aspects. Further research is needed to determine how to modulate the progression of fibrotic capsule formation in FBR artificially.

Abstract
BACKGROUND Breast implant capsule development and behavior are mainly determined by implant surface combined with other external factors such as intraoperative contamination, radiation or concomitant pharmacologic treatment. Thus, there are several diseases: capsular contracture, breast implant illness or Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL), that have been correlated with the specific type of implant placed. This is the first study to compare all major implant and texture models available in the market on the development and behave of the capsules. Through a histopathological analysis, we compared the behavior of different implant surfaces and how different cellular and histological properties give rise to different susceptibilities to develop capsular contracture among these devices. METHODS A total of 48 Wistar female rats were used to implant 6 different types of breast implants. Mentor®, McGhan®, Polytech polyurethane®, Xtralane®, Motiva® and Natrelle Smooth® implants were employed; 20 rats received Motiva®, Xtralane® and Polytech polyurethane®, and 28 rats received Mentor®, McGhan® and Natrelle Smooth® implants. The capsules were removed five weeks after the implants placement. Further histological analysis compared capsule composition, collagen density and cellularity. RESULTS High texturization implants showed the highest levels of collagen and cellularity along the capsule. However, polyurethane implants capsules behaved differently regarding capsule composition, with the thickest capsules but fewer collagen and myofibroblasts than expected, despite being generally considered as a macrotexturized implant. Nanotextured implants and microtextured implants histological findings showed similar characteristics and less susceptibility to develop a capsular contracture compared with smooth implants. CONCLUSIONS This study shows the relevance of the breast implant surface on the definitive capsules' development, since this is one of the most differentiated factors that determine the incidence of capsular contracture and probably other diseases like BIA-ALCL. A correlation of these findings with clinical cases will help to unify implant classification criteria based on their shell and their estimated incidence of capsule-associated pathologies. Up to this point, the establishment of additional groups is recommended as nanotexturized implants seem to behave differently to pure smooth surfaces and polyurethane implants present diverse features from macro- or microtextured implants.

Abstract
For decades, implant-based breast augmentation has been one of the most performed surgical procedures for cosmetic purposes around the world. Hence, novel manufactured implants should be critically investigated to prove them safe and effective. Here, the authors describe the first independently conducted clinical study on Nagor Impleo textured round breast implants. For this retrospective study, outcomes of 340 consecutive female patients undergoing primary cosmetic breast augmentation were analyzed. Demographic and surgical data as well as outcomes and complications were evaluated. Furthermore, a survey concerning effectiveness and aesthetic satisfaction after breast augmentation was examined. All 680 implants were placed in a submuscular plane with incisions at the inframammary fold. The main indications for surgery were hypoplasia and hypoplasia with asymmetry. The mean implant volume was 390 cc and the main type of projection was high profile. The most common complications were hematoma and capsular contracture (0.9 percent, respectively). The overall revision rate for complications was 2.4%. Additionally, almost all patients showed increased quality of life and aesthetic satisfaction after a breast augmentation. Hence, all patients would undergo breast augmentation again with these newly launched devices. Nagor Impleo implants demonstrate a low complication rate and high safety profile. Although high aesthetic satisfaction and quality of life results were achieved, analysis of an even larger series over a longer period of time would be beneficial to evaluate the reliability of this implant.

Abstract
Breast implants are widely used for reconstructive and/or cosmetic purposes. Inflammations and infections of breast implants represent important complications in clinical practice. The proper management of complications is necessary: diagnostic imaging plays a key role in detecting sites of inflammation and/or infection. The present review aims to illustrate the radiological findings of these conditions with different imaging techniques, such as mammography (MX), ultrasound (US), magnetic resonance imaging (MRI), and nuclear medicine imaging. A knowledge of these findings is essential for radiologists and nuclear medicine physicians to provide helpful information for the clinical management of these complications.

Abstract
BACKGROUND The inframammary approach is one of the most commonly used incisions in breast augmentation. There are many suture methods for inframammary incisions; however, no one method has proven optimal. We modified the traditional three-layer suture method according to the inframammary fold (IMF) cadaver dissection results. This study aims to investigate whether using a modified suture method can improve postoperative outcomes. METHODS Cadaver dissections were performed in order to clarify the anatomy of the IMF. From June 2013 to December 2017, a retrospective study of primary breast augmentation patients subjected to the inframammary approach was conducted. Patients were divided into two cohorts: the traditional suture method and the modified suture method. The patient's demographics, specifics of breast augmentation procedures, complications, and scar assessment were analyzed. Univariate and multivariable analyses were used to determine differences between the two cohorts. RESULTS One hundred eighty-four patients were included: 75 patients were subjected to the traditional suture method, and 109 patients were subjected to the modified suture method. Wound-related adverse events (p = 0.026) and IMF-indented scarring (p = 0.014) were significantly different between the two groups. Multivariable analysis showed that the suture method was the most influential factor related to IMF-indented scarring (OR = 16.9), followed by BMI (OR = 2.9). CONCLUSIONS We defined a new suture method for the inframammary incision in primary breast augmentation. This modified suture method reduces the occurrence of wound-related adverse events and IMF-indented scarring.

What is the best technic to dislodge Staphylococcus epidermidis biofilm on medical implants? BMC Microbiol 2022; 22:192. [PMID: 35933363 PMCID: PMC9356421 DOI: 10.1186/s12866-022-02606-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Accepted: 07/19/2022] [Indexed: 11/23/2022] Open
Abstract
Background Bacterial biofilm can occur on all medical implanted devices and lead to infection and/or dysfunction of the device. In this study, artificial biofilm was formed on four different medical implants (silicone, piccline, peripheral venous catheter and endotracheal tube) of interest for our daily clinical and/or research practice. We investigated the best conventional technic to dislodge the biofilm on the implants and quantified the number of bacteria. Staphylococcus epidermidis previously isolated from a breast implant capsular contracture on a patient in the university hospital of Dijon was selected for its ability to produce biofilm on the implants. Different technics (sonication, Digest-EUR®, mechanized bead mill, combination of sonication plus Digest-EUR®) were tested and compared to detach the biofilm before quantifying viable bacteria by colony counting. Results For all treatments, the optical and scanning electron microscope images showed substantial less biofilm biomass remaining on the silicone implant compared to non-treated implant. This study demonstrated that the US procedure was statistically superior to the other physical treatment: beads, Digest-EUR® alone and Digest-EUR® + US (p < 0.001) for the flexible materials (picc-line, PIV, and silicone). The number of bacteria released by the US is significantly higher with a difference of 1 log on each material. The result for a rigid endotracheal tube were different with superiority for the chemical treatment dithiothreitol: Digest-EUR®. Surprisingly the combination of the US plus Digest-EUR® treatment was consistently inferior for the four materials. Conclusions Depending on the materials used, the biofilm dislodging technique must be adapted. The US procedure was the best technic to dislodge S. epidermidis biofilm on silicone, piccline, peripheral venous catheter but not endotracheal tube. This suggested that scientists should compare themselves different methods before designing a protocol of biofilm study on a given material.

Abstract
Breast implantation (BI) is the most common plastic surgery worldwide performed among women. Generally, BI is performed both in aesthetic and oncoplastic procedures. Recently, the prevalence of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) or breast implant illness (BII) has aroused concerns. As a result, several countries, like Australia, Korea or the United Kingdom, introduced national registries dedicated to the safety and quality of BI surgeries. This narrative review aimed to focus on the clinical challenges, management and the current state of knowledge of BI. Both short and long-term outcomes of BI are determined by various alternatives and differences, which surgeons must consider during the planning and performing breast augmentation along with further complications or risk of reoperation. Proper preoperative decisions and aspects of surgical technique emerged to be equally important. The number of performed breast reconstructions is increasing, providing the finest aesthetic results and improving patient’s quality of life. Choice of prosthesis varies according to individual preferences and anatomical variables. A newly diagnosed cases of BIA-ALCL with lacking data on prevention, diagnosis, and treatment are placing it as a compelling medical challenge. Similarly, BII remains one of the most controversial subjects in reconstructive breast surgery due to unspecified diagnostic procedures, and recommendations.

Comparative Analysis of Prepectoral versus Subpectoral Implant-based Breast Reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3709. [PMID: 34422525 PMCID: PMC8376352 DOI: 10.1097/gox.0000000000003709] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 05/27/2021] [Indexed: 02/01/2023]
Abstract
Recent advances in mastectomy and reconstruction have allowed for an evolution in implant-based breast reconstruction to a muscle-sparing, prepectoral approach. Advantages of this technique may include reductions in postoperative pain, shorter hospitalization, less narcotic usage, and improved aesthetic outcomes. Postoperative complication rates are described as comparable to subpectoral techniques; however, little comparative data exist to adequately assess prepectoral versus subpectoral implant placement. Methods To address this knowledge gap, we performed a single institution retrospective review of 186 (83 prepectoral, 103 subpectoral) consecutive immediate breast reconstructions. All cases were tracked for a minimum of 2 years between 2016 and 2021. Results Prepectoral patients demonstrated an overall higher seroma rate (P = 0.001), with all other postoperative complications being comparable. Prepectoral patients tolerated higher intraoperative tissue expander fill volumes (P < 0.001), shorter hospital stays (P = 0.007), fewer clinic visits for tissue expansion (P < 0.001), and experienced less animation deformity (P = 0.005). Both groups demonstrated similar pain scores (P = 0.65) and needs for narcotics (P = 0.8) as well as comparable scores of capsular contracture (P = 0.791). Conclusions Our comparative analysis of consecutive immediate implant-based breast reconstructions finds prepectoral reconstruction to be safe and effective. Compared with subpectoral reconstruction, the prepectoral approach may offer quicker tissue expansion, less postoperative office visits, less need for muscle relaxants, and a shorter hospital stay with a comparable complication profile.
